[0002] Cooling rollers are widely used in paper box printing, papermaking and other production lines. Their main function is to cool down materials with high temperatures to a suitable temperature. The main function of cooling rollers in the printing process is to cool and flatten the materials. Different positions in the printing process need to be printed multiple times, and a drying device must be used to quickly dry the ink of the previous printing and achieve reasonable printing suitability. The material after drying has a higher temperature, and the material needs to be cooled before entering the next printing, so cooling rollers are used for cooling.

[0003] For example, the utility model with the publication number CN216466881U discloses a high-efficiency cooling roller for printing, which belongs to the field of cooling technology. It includes a cooling rack and a circulating cooling assembly, wherein the cooling rack includes a mounting bracket, a hollow cooling roller, a rotating joint and a cooling coil, wherein both ends of the hollow cooling roller are rotatably mounted on the mounting bracket through bearings, the cooling coil is fixedly mounted on the inner wall of the hollow cooling roller, the rotating joint is mounted on the rotating joint through a bearing, and one end of the cooling coil is connected to the rotating joint; the temperature of the coolant flowing from the water tank to the chiller is conveniently reduced by a chiller, and is transported to the cooling coil through a water delivery mechanism, so as to reduce the temperature of the surface of the hollow cooling roller, achieve a rapid cooling effect, and the coolant inside the cooling coil flows into the water tank through a return pipe, which is convenient for continued recycling, greatly avoiding the waste of water resources and improving the cooling effect.

[0004] According to the above device, the setting of the return pipe enables the device to recycle the coolant, thereby avoiding the waste of water resources. However, after the above device has been used for a long time, it is difficult to clean and wipe the surface of the cooling roller, which can easily lead to a decrease in the efficiency of the printing effect and cause blurred printing. Therefore, a cooling roller for printing is proposed to address the above problem. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 5 As shown, the utility model provides a cooling roller for printing, including a placement rack 1, a motor 2 is arranged on one side of the placement rack 1, the output shaft end of the motor 2 is rotatably connected to an inner tube 3, the outer surface of the inner tube 3 is fixedly connected to an outer tube 4, an arc groove plate 5 is movably connected to one side of the placement rack 1, a side of the arc groove plate 5 away from the placement rack 1 is slidably connected to an arc plate 6, one side of the arc plate 6 is fixedly connected to a fixed plate 7, the bottom of the fixed plate 7 is fixedly connected to a cleaning sponge 8, a side of the arc groove plate 5 close to the placement rack 1 is fixedly connected to a moving block 9, the bottom of the moving block 9 is fixedly connected to a first telescopic rod 10, an upper surface of one side of the inner tube 3 is slidably connected to an arc clamp 11, and one side of the arc clamp 11 is fixedly connected to a second telescopic rod 12.

[0023] First, install the cooling roller on the placement frame 1. After installation, push the arc clamp 11 through the second telescopic rod 12 to further clamp and fix the cooling roller. Then, water is injected into the cooling roller through the water inlet pipe 13. When the water volume inside the cooling roller reaches a certain height, the water flow will flow back through the return pipe at the bottom, thereby improving the recycling of water resources. Then, the cooling roller is further cooled by wind through the cooling fan 16. When too much dye appears on the surface of the cooling roller, first push the arc plate 6 on one side of the fixing plate 7 through the arc groove plate 5 to push the cooling roller. When the cleaning sponge 8 is not in use, the arc plate 6 is moved through the arc groove plate 5 by pushing the handle so that the fixed plate 7 is not at the top of the cooling roller, so as to avoid affecting the cooling effect of the cooling roller by the cooling fan 16.

[0024] like Figure 1 , Figure 3 As shown, a water inlet pipe 13 is sleeved on one side of the placement rack 1, and a water return pipe is fixedly connected to the bottom of the water inlet pipe 13.

[0025] The above scheme is adopted: through the water inlet pipe 13 on one side of the placement frame 1, the device can inject water into the cooling roller to facilitate the refrigeration effect of the cooling roller. When the water volume in the cooling roller reaches a certain height, it can flow back through the return pipe, thereby achieving a recycling effect and avoiding waste of water resources.

[0026] like Figure 4 , Figure 5 As shown, a cooling fan 16 is fixedly connected to the top of the placement rack 1, a push handle is fixedly connected to one side of the arc plate 6, and a U-shaped block is rotatably connected to one side of the placement rack 1 close to the arc slot plate 5.

[0027] The above-mentioned scheme is adopted: by placing the cold air fan 16 on the top of the rack 1, the cooling roller can be better cooled, and the double-effect cooling effect is better. The pushing plate on one side of the arc plate 6 is convenient for moving the arc plate 6. When the cleaning sponge 8 is not used, it is ensured that the fixed plate 7 is not on the top of the cooling roller to avoid blocking the cooling effect of the cold air fan 16. The U-shaped block on one side of the rack 1 can clamp and fix the cleaning sponge 8 after it is moved to avoid the movement of the cleaning sponge 8 during use.

[0028] like Figure 1 , Figure 5As shown, the inner tube 3 is made of copper, the outer diameter of the arc plate 6 is matched with the inner diameter of the arc slot plate 5, and a slot matching the moving block 9 is provided on one side of the placement rack 1.

[0029] The above scheme is adopted: the material of the inner tube 3 is copper, so that the cooling roller has better thermal conductivity, the arc plate 6 is adapted to the arc groove plate 5, so that the arc plate 6 can be easily moved through the arc groove plate 5, and the slot on one side of the placement rack 1 also facilitates the moving block 9 to be able to move through the first telescopic rod 10.

[0030] The working principle and use process of this utility model:

[0031] First, install the cooling roller on the placement rack 1. After installation, push the arc clamp 11 through the second telescopic rod 12 to further clamp and fix the cooling roller. Then, inject water into the cooling roller through the water inlet pipe 13 to enable it to be cooled better. When the water inlet pipe 13 is filling with water, when the water volume inside the cooling roller reaches a certain height, the water flow will flow back through the return pipe at the bottom, thereby improving the recycling of water resources and avoiding the waste of water resources. Then, the cooling roller is further cooled by wind through the air cooler 16. The double-effect refrigeration can improve the cooling effect of the cooling roller. When too much dye appears on the surface of the cooling roller, first push the fixing plate The arc plate 6 on one side of 7 is pushed to the top of the cooling roller by the arc groove plate 5, and then the fixed plate 7 is clamped by the U-shaped clamping block to avoid movement during subsequent use, and then the moving block 9 is driven by the first telescopic rod 10 to move the cleaning sponge 8 downward and fit it to the surface of the cooling roller, so as to facilitate wiping the dye on the surface of the cooling roller, thereby avoiding the subsequent cooling roller easily causing a decrease in the efficiency of the printing effect and causing blurred printing. When the cleaning sponge 8 is not in use, the arc plate 6 is moved through the arc groove plate 5 by pushing it, so that the fixed plate 7 is not at the top of the cooling roller, so as to avoid affecting the cooling effect of the cooling fan 16 on the cooling roller.
